Application filed E'e'bruary 5, 1901. Serial No. 46,067. No model.)

To all whom it may concern: furcated. Pivoted between the bifurcated Beit known that I, WILLIAM H. KERSEY, ends of link 16 are the ends of aU-shaped a citizen of the United States, residing at Inyoke 17, the base17 of which lies within a dianapolis, in the county of Marion and Stateslot 18, formed in a lever 19, which is pivoted 55 of Indiana, haveinvented a new and useful at 2O to a stationary cross-bar on the table.

Secured tothe under side perposition, so as to form a continuation of of back 7 is a rack 8, theteethv of which are table 6, yoke 17 lies at the forward end of slot 85arranged to be engaged by the forward end 18, and the joint between saidyoke and link of a brace 9, pivoted at 10 andprovided with 16 liesslightly below aline drawn between a spring 11, which tends normally tothrow the opposite ends of the link and yoke, lugs the outer end ofsaid4 brace upward. Piv- 21 being then in engagement with the fingersoted to the under side-of back 7 is a bar 12, of yoke 17. The leg-restis thus braced and 9o 4o having an offset portion or guard 13, whichlocked in its upper position.

Pivoted to which emerges from lever 19 close toits end roo 5o the lower end of each bracket 15 is one end in positionto engage the rear end of a plate of a link- 16, the opposite end ofwhich is bi- 31, which is secured to the rest 22 between the ears ofguide 23. rod 30 projects into the forward end of slot 18, and said rodis held in engagement with the base 17' of yoke 17 by means of a spring32, which lies between lever 19 and an adjustable head 33, secured tothe rod, the tension of said spring being such as to withdraw theforward end of rod 30 from engagement with plate 31. For the purpose ofbreaking the joint at the point of connection between link 16 and yoke17 I pivot upon link 16 a slotted link 34:, the upper end of which issecured to the crank 35 of a releasing-rod 36. The rods 36 are eachprovided upon one end with a second crank, 38, both of which are broughtclose to the edge of the table and provided with finger-pieces 39, bymeans of which the corresponding rod 36 may be rocked so as to operatelink 34.

Projecting from the rear end of lever 19 is an arm or finger 40, whichwhen the leg-rest is thrown down to its last position, as shown indotted lines in Fig. 3, will engage a stationary cross-bar secured tothe table, and thus form a rigid brace for the leg-rest in thatposition.

The operation is as follows: With the parts in the position shown infull lines in Fig. 1 the pivotal connection between link 16 and yoke 417 is dropped below the line connecting the ends, the lugs 2l engagingthe fingers of the yoke 17, so as to prevent further movement. The base17 of the yoke 17 has been forced to the forward end of slot 18, thusforcing rod 30 against the action of spring 32, so as to project theforward end thereof through the forward end of lever 19 and intoengagement with the end of plate 31, thus-preventing any movement of theend of lthe lever and forming a rigid brace for each leg-rest. When eX-tended, the foot-board 27 lies in the same plane with its leg-rest 22and top 6, the arm I 28 of the foot-board engaging the under side of itsrest 22. The operator by swinging pawl 14 throws guide 13 out beyond theends of the teeth of rack 8, and thus throws brace 9 from engagement'wthsaid teeth by swinging back 7 upward. The first action is to pull yoke17 backward to the rear end of slot 18. Rod 30 follows the yoke due tothe action of spring 32, the forward end of said rod being thusimmediately withdrawn from engagement with plate 31. A further upwardswing of the back 7 allows both leg-rests 22 to swing downward, theforward ends of levers 19 sliding in grooves 26 of the guides 23. Justbefore the levers 19 reach the position shown in dotted lines in Fig. 1the forward ends thereof have been moved so as to bring sockets 29 intoengagement .with the rear ends of arms 28, and thus automatically swingthe foot-boards 27 about their pivots, as indicated.

It is sometimes desirable to adjust one or the other or both leg-restswithout an adjustment of the swinging back 7. For this purpose theoperator by pressing the proper fin- The opposite end of ,l ger-piece 39swings the proper rod 36 so as to cause its link 33 to break the toggleformed by the link 16 and yoke 17, thus drawing the corresponding yoke17 to the rear of its slot 18 of the lever 19 of the leg-rest to beoperated, when said rest may be dropped to the position shown in dottedlines in Fig. 2.

The back 7 is normally locked in the same plane as the top 6 by pawl 14,which is provided with a projecting lip 14', arranged to pass under acatch 14, secured to the body of the top 6.
